The Fleetwings Model 36 was a plywood skinned aerial target with the military designation PQ-12A. This particular aircraft was the prototype and it first flew on 5 December 1941 as NX37010 powered by a Franklin O-300-7 engine of 175 hp. Test pilot William H. Engle was at the controls. (Prototype serial 41-39057 for XPQ-12 not taken up.) On 18 Sept 1942, NX37010 was cancelled and military serial 41-39098 was applied for an XPQ-12A. Subsequent modifications included a simplified nose leg and wheel fairing and substitution of a Lycoming O-435-5 engine of 225 hp. The latter necessitated a larger cowling as seen on the photo of 41-39045. Collection holder William Engle is the son of Fleetwings test pilot William H. Engle.

Designated as an Assault Drone, the plywood skinned BQ-2A was powered by 2 x Lycoming R-680-13 engines of 300 hp each. A 2000 lb bomb could be carried in a compartment just aft of the wing. It shares the Fleetwings Model 37 number with the XBQ-1 and has the same airframe, however the fixed landing gear was jettisonable for better performance. A TV camera mounted in the LH wing leading edge allowed its guidance onto target from a mother-ship. First flight was on 21 August 1943. The design was deemed to be too expensive for operational use, so the program was cancelled in December 1943.

The Fleetwings Model 37 was an Assault Drone with military designation BQ-1. It was plywood skinned and was powered by 2 x Franklin O-405-7 engines of 250 hp each. A 2000 lb bomb could be carried in a compartment just aft of the wing. In this photo, the 48 ft span wings with leading edge slots are well illustrated. A TV camera mounted in the aircraft allowed its guidance onto target from a mother-ship. On 17 July 1944 the aircraft was wrecked in an engine failure induced forced landing near Wright Field/OH, resulting in cancellation of the program.
